Answer: 5.5 which is choice B</h3>
Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle
opposite the reference angle is the vertical side x
adjacent to the reference angle is the horizontal side 15
We'll use the tangent rule. Make sure your calculator is in degree mode.
tan(angle) = opposite/adjacent
tan(20) = x/15
15*tan(20) = x <<-- multiply both sides by 15
x = 15*tan(20)
x = 5.45955 <<--- use calculator; this is approximate
x = 5.5 <<--- round to one decimal place
Answer:
0.8
Step-by-step explanation:
We see that there are 5 equal sections, 4 of which have beavers on them.
P(beaver) basically means that we want to find the probability of landing on a beaver; in other words, we're looking for a fraction:
(# sections you can land on a beaver) / (total # of sections)
Here, the number of sections you can land on a beaver is 4, while the total number of sections is 5. So, P(beaver) = 4/5.
Thus, the answer is 4/5, which can be written as the decimal 0.8.
Hope this helps!
You would combine like terms to get x^2 - 6x + 34
The cistern is losing approximately 3.963 gallons of water per hour.
<u><em>Explanation</em></u>
A cistern is leaking 0.25 liters of water per minute.
<u>We know, 1 gallon = 3.785 liters</u>
So, 0.25 liters = gallons
That means, the cistern is losing 0.06605....gallons of water per minute.
So, the amount of water losing in 1 hour or 60 minutes <em>(Approximately)</em>
